AUTOMATIC SAFETY-BRAKE FOR HORSE=POWERS.

SPECIFICATION forming part of Letters Patent No. 305,759, dated September 30, 1884.

Application filed February 14, 1884. (No model.) i

To all whom, it may concern.-

Be it known that I, TILLIAM L. REMING- TON, of Meriden, in the county of New Haven and State of Connecticut, have invented a new and Improved Automatic Safety-Brake for I-Iorselowers, of which the following is afull, clear, and exact description.

The object of this invention is to provide effective and reliable means for automatically applying the brake to the band-wheel of horsepowers in case the belt should break or accideutally run off from the band-wheel or pulley, thus preventing all danger of injury to the horses or power that might result from thus relieving the horse-power of the resist: ance of the machine to which the horse-power is attached; and the invention consists, principall y, of a system of levers applied to the ordinary brake-lever in such manner that a downward movement of the main horizontal lover of the system will shove forward the brake-lever and apply the brake.

The invention also consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l. is a side elevation of a horse-power having my invention applied thereto, the parts being in position ready to act in case the main belt should run off or break; and

Fig. 2 is a side elevation of the band-wheel and brake, the parts 'being shown in the position they assume for automatically applying the brake.

A represents the horse-power; B, the bandwheel thereof; 0, the belt passing over the band-wheel I; and pulley l) of the machine to be operated by the horse-power, and E repre sents the ordinary brake lever or bar, which is pivoted at a and provided with the brakeshoe 1), which is arranged to come'against the periphery of the band-wheel B when the upper end of the lever E is pressed toward the said band wheel B.

F is the bar by which the brake-lever E may be operated in the ordinary way.

Attached to the main brake lever or bar E by the plate 0 and pivot 0 is the upright bar or lever G, the upper end of which is confined in place and limited in its movement by the bent keeper H, attached to the side of the horse-power.

Attached to lever or bar G by the plate (I and pivot d is the main horizontal lever I.

This is connected back of the pivot d to the .upon the belt 0 when the belt is in place, as

shown in Fig. 1, and the bolt f passes through the slot h made in the upper end of the arm K, and also through the slot 71/ made in the horizontal lever I, so that by means of these slots the arm K is adapted to be adjusted both vertically and horizontally, as circumstances require.

hen the horses are placed upon the horsepower and the belt 0 is in place on handwheel 13 and pulley D, the outer end of the lever I will be lifted and the pulley g placed upon the belt 0, which will hold the lever I in elevated position, where the connecting rod or plate J will hold the brake-lever E and brake-shoe b drawn backward away from the band-wheel B, as shown in Fig. 1.

\Vhcn all is running right, if it is desired to stop the machine the brake-shoe b will be applied to the band-wheel B in the ordinary manner by pressing forward upon. the bar F;

but in case the belt 0 should break or run off from the band-wheel B and pulley D, the lever I will be left unsupported and will drop of its own weight and that of the arms J K and pulley gto the position shown in lFig. 2,whieh will first draw the bar or lever G backward as far as the keeper II will permit, and then, through. connecting rod or plate J, will force the upper end of the brake-lever E forward, and thus automatically apply the brake-shoe b to the band-wheel B and retard and finally stop the motion of the horsepower, thus avoiding all danger of injury to the horses and horse power, which might occur if the power were permitted to run without resistance.
